SEISA GC Coupling

Gear coupling that automatically adjusts eccentricity, deflection angle, and errors of the shaft directions

It adjusts and absorbs parallel offset or tilting, and prime mover torque is fully transmitted.
Misalignment between the shafts is corrected by the crowning teeth, ensuring high durability and excellent wear resistance.
As the center and housing are separated, easy assembly/disassembly and lightweight/compact size are achieved.
As it produces no difference in rotation angles between two shafts due to coupling deflection, it certainly transmits torque.

Features

Correction of eccentricity, misalignment, and errors of the shaft directions

Prime mover torque is fully transmitted despite the presence of misalignment (offset and Angular) of shafts to a certain extent.
It automatically adjusts and absorbs parallel offset or tilting of the coupled shafts even if it occurs during operation, avoiding excessive loading on the shaft and bearing and thus protecting the machine.

Excellent wear resistance

Flexible coupling using crowned teeth features high durability and excellent wear resistance.

Compact size and easy mounting/dismounting

Separate center and case design allow for easy mounting/dismounting, and minimal installation space with its compact and lightweight design.
Additionally, a compact sleeve-type GL model is available.

Consistent rotation without misalignment

Unlike other flexible couplings, SEISA GC Coupling produces no difference in rotation angles between two shafts due to coupling deflection, making it the optimum choice for line shaft coupling, high-speed, and heavy-duty applications.

Easy shaft alignment and inspection

The length of the coupling center is longer compared to the coupling case width, allowing for easy shaft alignment by moving the coupling case within the range of boss length.
Inspection of the gear teeth also becomes easier.
